INTRODUCTION 

 

What is the AMP CENTRAL?  

 

The  Amp  Central  is  our  answer  for  the  modern  guitarists  who  still  love  their  tube  based 
amplifiers, in every situation, even where low volumes are not allowed.  
Amp  Central,  as  the  name  suggested  is  a  hub  for  connecting  your  amplifier  to  the  outside 
world, without the need of a real cabinet and at any volume.   
 
 

THE CONCEPT  

 
Since a few years, digital systems became very popular in the guitar amplifier market, replacing 
a real amp in most of the “inconvenient” gig where a proper stage volume was not possible or 
for example, during exercise sessions late at night.  
What is missing here is what we call the “total experience” of a real amp-speaker interaction, 
and we do think this combo is still unsurpassed in terms of the feeling under player’s finger, but 
at  the  same  time  we  realize  that  needs  are  constantly  moving  and  music  is  always  evolving. 
What  could  we  do  to  improve  the  experience  of  a  “fake”  or  profiled  amplifier,  played  with 
headphones, which in most cases yields bad results? 
Well, we thought of a solution and we brought a couple of different technologies into the game, 
one very old and one not so old, respectively called 

Dummy Load

 (in our case a Reactive Load) 

and the 

Impulse Response

 technology. 

   
It’s a known fact your tube based amplifier needs to have a cabinet wired to the output jack 
when used, or at least a proper load, the potential penalty could be the reduction of the life of 
its output transformer.  
 
With this in mind we built the very first stage of the Amp Central, by creating a proper Dummy 
Load, or better, a Reactive/Resistive Load, to mimic at the closest possible approximation of a 
real  cabinet.  We've  gone  fully  analog  with    the  best  components  available  in  the  real  world, 
something  that  audiophile  experts  will  appreciate.  No  digital  processing  or  equalization  is 
applied there, since we do believe your amplifier needs a proper analog load to sound and feel 
at its best.  
 
And where do we go from there? The amp is now safe and running, while no sound will come 
out of it. Well, at this point we decided to embrace digital world, with Impulse Responses*.  
 
Basically,  with  Amp  Central  we  wanted  to  offer  the  best  of  both  worlds,  offering  you  the 
possibility  of  playing  your  favorites  amplifiers  and  not  their  simulations,  with  some  Impulse 
Response 

of 

your 

favorite 

cabinets.  

This will be YOUR and not someone else's sound. So your own amp(s) and possibly your own 
cab’s I.R.(s).
